You divide 1,060 with 30%

1,060 - 30% (30) = 742!

Val scored 742 points!

If Val scored 30% less than Peeta, that means Val scored 100-30=70% of what Peeta scored. So take 70% times 1060 points, this gives the answer 742. Hope this helps ;)

CAF and EFA are congruent because they are corresponding angles of parallel lines cut by a transversal. ∠GAC ≅ ∠HFD by the transitive Property of Congruence.

What are congruent angles?

Angles that are of the same measurement are called congruent.

Suppose that two angles ∠A and ∠B are of the same measure,

then

[tex]m\angle A = m\angle B[/tex]

is the notation to say that they are of same measurement, where the small m shows that its the measurement of the angles they're preceding.

We write the congruency between them as;

[tex]\angle A \cong \angle B[/tex]

In the figure BC || DE .

Angles

CAF and EFA are congruent because they are corresponding angles of parallel lines cut by a transversal.

GAC and DFE are not congruent

CAF and EFH are not congruent

GAB and EFA are not congruent

∠GAC ≅ ∠AFE because they are corresponding angles of parallel lines cut by a transversal.

∠AFE ≅ ∠HFD by the Vertical Angles Theorem.

Therefore, ∠GAC ≅ ∠HFD by the transitive Property of Congruence.

∠AFD = ∠AFE

Two angles that are equal to the same angle must themselves be equal.

In below diagram, line AB is parallel to CB.
i.e. AB∥CD
∠EGB = 57°
Find ∠EHD.

Answers

Because line AB is parallel to CB, we know that angles EGB and EHD are corresponding angles.

Corresponding angles are congruent. Why, you ask? Well if you take a look at the diagram, you'll realize that angles EGB and AGH are vertical angles. Because of this, they're congruent. AGH and EHD are alternate interior angles, which are congruent.

Knowing that EHD is a corresponding angle to EGB, we know that the measure is 57 degrees.

In the given diagram, line AB is parallel to CB. i.e. AB∥CD ∠EGB = 57°

then the value of ∠EHD = 57°

In this diagram, since AB is parallel to CD, we can infer that ∠EGB and ∠EHD are corresponding angles, and corresponding angles are congruent when a pair of parallel lines are intersected by a transversal. Given that ∠EGB = 57°, we conclude that ∠EHD is also 57° based on the properties of corresponding angles. Thus, ∠EHD = 57°.

When two parallel lines are intersected by a transversal, the corresponding angles formed on either side of the transversal are congruent. In this case, we are given that line AB is parallel to line CD, which implies that ∠EGB and ∠EHD are corresponding angles.

Given: ∠EGB = 57° (Given in the diagram)

Since AB || CD, ∠EGB ≅ ∠EHD (corresponding angles are congruent).

Therefore, ∠EHD = ∠EGB = 57°.

Hence, ∠EHD is also 57° based on the properties of corresponding angles.

In mathematical terms, we use the property of corresponding angles formed by a transversal intersecting two parallel lines to establish the congruence between ∠EGB and ∠EHD. This property is a fundamental aspect of geometry dealing with angles and parallel lines.

The ratio of the number of black circles to the number of black squares is 3:8
Work out what fraction of all the shapes are circles.

Answers

Answer:

the fractions of all the shapes are circles can be obtained would be computed as:  

                      [tex]\frac{450}{1600}=\frac{9}{32}[/tex]        

Step-by-step explanation:

The fraction of the number of white shapes to the number of black shapes is 5/11.

Let us consider that there are:

500 white shapes1100 black shapes

As the fraction of the number of white circles to the number of white squares is 3:7

It means out of 10 total parts, 3/10 are white circles and 7/10 are white squares.

Calculating Number of white circles:

                                                           [tex]\frac{3}{{10}} \times 500=150[/tex]

                                                           

Calculating Number of white squares:

                                                            [tex]\frac{7}{{10}} \times 500=350[/tex]

As the fraction of the number of black circles to the number of black squares is 3:8.

Calculating Number of black circles:

                                                            [tex]\frac{3}{{11}} \times 1100=300[/tex]

Calculating Number of black squares:

                                                            [tex]\frac{8}{{11}} \times 1100=800[/tex]

As

the total number of circles is 150 + 300 = 450, and the total number of shapes is 500 + 1100 = 1600

Therefore, the fractions of all the shapes are circles can be obtained would be computed as:

                            [tex]\frac{450}{1600}=\frac{9}{32}[/tex]

since we know this is a rectangle and the lines are diagonals we can assume they create right triangles. For line N we set up the Pythagorean Theorem which is a^2 + b^2 = c^2 and to find N we plug in 9 for a and 12 for b. 9^2 + 12^2 = c^2 c^2 = 225 so now we find the square root of c^2 so c or in this case N = 15, now we repeat this same exact sequence for O but N is now our base and 8 is our height of the triangle so we will plug in 8 for a and 15 for b: 8^2 + 15^2 = c^2 c^2 = 289 and the square root of 289 is 17.

Because the ratio of orange marbles to green marbles is ___ in the​ population, the expected number of green marbles is ___ times the number of orange marbles in the representative sample. There should be ___ green marbles.

Answers

9 green marbles are expected in the representative sample.

The expected number of green marbles is 0.27 times the number of orange marbles in the representative sample.

Step-by-step explanation:

Given that,

A bag contains 77 orange marbles and 21 green marbles.A representative sample contains 33 orange ​marbles  and the green marbles not known.So, the expected number of green marbles can be assumed as 'x'.

The ratio of orange marbles to green marbles is in proportion to the ratio of orange marbles to green marbles in the representative sample.

To find the value of x :

The proportions are 77/21 = 33/x

Cross multiplying the denominators and keeping x alone on one side,

x = (33 × 21) ÷ 77

x = 693 ÷ 77

x = 9 green marbles.

Therefore, the number of green marbles expected in the representative sample is 9.

To find the how many times the green marbles is to the number of orange marbles in representative sample = 9/33 = 0.27 times.

The green marbles is 0.27 times to orange marbles in the representative sample.

Step-by-step explanation:

Let x represent the first no

Then x+2 represents the second number

Turn the question to an equation= x - (x +2) =708

Therefore, 2x + 2= 708

2x= 708-2

2x= 706

x= 353 and x+2= 355

Hope you understand, please mark brainliest.

Answer:

The first number is 353, and the second is 353 + 2, or 355.

Step-by-step explanation:

Represent the first number by n and the next by n + 2.  

Then n + (n + 2) = 2n + 2 = sum of the two numbers = 708.

Subtracting 2 from both sides yields 2n = 706.  Dividing both sides of this latest result by 2 yields n = 353.

The first number is 353, and the second is 353 + 2, or 355.

3 887 860 rounded to the nearest million is 4 000 000.

From the given number 3 887 860, stating the place value of each digit

We have 0 ones (or unit), 6 tens, 8 hundreds, 7 thousands, 8 ten thousands, 8 hundred thousands and 3 million.

Hence, the number we are rounding is 3 (since we are asked to round to the nearest million)

To round a number, we either round up or round down.  

If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down; and if the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up.

Since, the number that follows the digit we are rounding is 8, then we round up. We round up by adding 1 to the digit we are rounding and turn the remaining numbers to zeros.

(3+1 = 4)

Hence, 3 887 860 rounded to the nearest million is 4 000 000.

Session

Answers

Answer: D) 111

Step-by-Step Explanation: In order to determine how many slices of sausage pizza were sold, you have to find out how many pepperoni and cheese pizza slices were sold as well. It says that 117 slices of pepperoni pizza were sold, so we don’t have to figure that one out. To find the cheese pizza slices that were sold, you have to subtract 117-34 because it says how many more pepperoni slices were sold than the cheese ones. The cheese pizza slices that were sold are 83 slices. So, to find the sausage pizza slices that were sold, you’re going to add 83 and 28, since the 28 more slices of sausage pizza was sold than the cheese. 83+28=111.

A ball is tossed between three friends. The first toss is 8.6 feet, the second is 5.8 feet, and the third toss is 7.5 feet, which takes the ball back to the starting point. What angles are formed by these tosses. Step by Step explanation.. Please

Answers

angles formed by these tosses are  [tex]79.45, 59.02[/tex] and [tex]41.53[/tex] degrees to the nearest hundredth.

Step-by-step explanation:

Here , We have a triangle with sides of length 8.6 feet, 5.8 feet and 7.5 feet.

The Law of Cosines (also called the Cosine Rule) says:

[tex]c^2 = a^2 + b^2 - 2ab (cosx)[/tex]

Using the Cosine Rule to find the measure of the angle opposite the side of length 8.6 feet:

[tex]c^2 = a^2 + b^2 - 2ab (cosx)[/tex]

⇒ [tex]c^2 -a^2 - b^2 = -2ab (cosx)[/tex]

⇒ [tex](cosx) =\frac{ c^2 -a^2 - b^2}{ -2ab}[/tex]

⇒ [tex](cosx) =\frac{(8.6^2 - 5.8^2 - 7.5^2)}{ ( -2(5.8)7.5)}[/tex]

⇒ [tex](cosx) =0.18310[/tex]

⇒ [tex]cos^{-1}(cosx) = cos^{-1}(0.18310)[/tex]

⇒ [tex]x = 79.45[/tex]

The Law of Sines (or Sine Rule) is very useful for solving triangles:

[tex]\frac{a}{sin A} = \frac{ b}{sin B} = \frac{c}{sin C}[/tex]

We can now find another angle using the sine rule:

⇒[tex]\frac{ 8.6 }{ sin 79.45} = \frac{7.5}{ sin Y}[/tex]

⇒[tex]sin Y = \frac{(7.5 (sin 79.45))}{ 8.6}[/tex]

⇒[tex]Y = 59.02 degrees[/tex]

So, the third angle =[tex]180 - 79.45 - 59.02 = 41.53 degrees.[/tex]

Therefore, angles formed by these tosses are  [tex]79.45, 59.02[/tex] and [tex]41.53[/tex] degrees to the nearest hundredth.

d=2r

12=2r

Divide by 2 on both sides

r=6

Plug 6 in for "r" in the area formula.

a=[tex]\pi[/tex]r^2

a=[tex]\pi[/tex]6^2
