During the weekend sale, a total of 360 T-shirts were sold from the initial stock of 800 T-shirts in packs of 4. This resulted in 440 T-shirts leftover in stock after the sale.

In the context of the store scenario, we have an initial stock of 800 T-shirts, which are sold in packs of 4 each. On Saturday, 20 packs are sold, resulting in a reduction of 20 packs times 4 shirts per pack, which equals 80 shirts. On Sunday, 70 more packs are sold, which corresponds to 70 packs times 4 shirts per pack, totaling 280 shirts sold on Sunday. Adding up the shirts sold on both days, we get 80 + 280, which equals 360 shirts sold in total during the weekend. To find the remaining stock, we subtract the total shirts sold from the initial stock: 800 shirts - 360 shirts = 440 shirts remaining after the sale.

Answer:

B-2/3

Answer:

B. 6.5 ≤ x

Step-by-step explanation:

Nathan's pay for the week, including x extra hours, will be ...

250.25 +9.50x

We want that to be at least 312, so the inequality is ...

250.25 +9.50x ≥ 312

9.50x ≥ 61.75 . . . . . . . . subtract 250.25

x ≥ 6.5 . . . . . . . . . . . . . . divide by 9.5

The graph showing a solid dot at x=6.5 and an arrow extending to the right will be the correct graph of this solution.

Answer:

4 Small, 6 Large

Step-by-step explanation:

We can start by finding values that would help add our two prices together.

We know that each large umbrella is $25, so if we keep adding until we can add up the umbrellas to 10, then we'll get our answer.

1 Large: $25

2 Larges: $50

3 Larges: $75

4 Larges: $100

5 Larges: $125

6 Larges: $150

Now don't forget, we need 10 umbrellas in total, and we know that we need 4 more umbrellas to get to 10, and we need 40 more dollars to get to 190.

40/10 = 4

6 Larges, 1 Small = $160

6 Larges, 2 Small = $170

6 Larges, 3 Small = $180

6 Larges, 4 Small = $190

the answer to this question would be c- 15.6

Answer:

3.52 × 10⁸

Step-by-step explanation:

Scientific notation is written in: Number that is in the ones place × 10^power.

Here, the number is 3.52, since 3 has the largest placement.

The power on the 10 should be the number of 0's on 352,000,000/3.52. That is 100,000,000. That number has 8 0's, so the power is to the 8th.

Putting that together, this number in scientific notation in 3.52 × 10⁸.

Answer:

11 degrees.

Step-by-step explanation:

"Angles T and U are a linear pair. Angle U measure (9x+6) and Angle T measures(6x+9). What is the value of x, in degrees?"

We know that a linear pair MUST add up to 180 degrees, therefore (9x+6)+(6x+9)= 180

Now for some algebra-

(9x+6)+(6x+9)= 180

6 and nine can both be divided by 3, so we will do that for simplicity:

((9x+6)+(6x+9)= 180)/3=

(3x+2)+(2x+3)=60

We will now separate the parenthesis, as they serve no purpose anymore.

(3x+2)+(2x+3)=60

3x+2+2x+3=60

Combine terms

5x+5=60

Take away the 5 to isolate the variables

5x+5=60

-5

5x=55

Divide by 5

5x=55

/5

x=11

The value of x is 11 degrees.

Answer: Option D

Step-by-step explanation:

Add 4x² to both sides  of the equation:

[tex]16x+8+4x^2=-4x^2+4x^2\\4x^2+16x+8=0[/tex]

The Quadratic formula is:

[tex]x=\frac{-b\±\sqrt{b^2-4ac}}{2a}[/tex]

You can identify that in this case:

[tex]a=4\\b=16\\c=8[/tex]

Substitute into the Quadratic formula:

[tex]x=\frac{-16\±\sqrt{(16)^2-4(4)(8)}}{2(4)}[/tex]

 [tex]x_1=-0.58\\x_2=-3.41[/tex]

Therefore, the graph of the equation above intersect the x-axis in two points.

The answer is:

D. The parabola intercepts the x-axis in two points.

[tex]x_{1}=-0.59\\\\x_{2}=-3.41[/tex]

To find the parabola intercepts, we need to use the quadratic formula. The parabola intercepts with the x-axis, are also called roots or zeroes.

The quadratic formula states that:

[tex]x=\frac{-b+-\sqrt{b^{2}-4ac } }{2a}[/tex]

We are given the parabola:

[tex]16x+8=-4x^{2} \\[/tex]

Which is also equal to:

[tex]4x^{2}+16x+8=0[/tex]

Where,

[tex]a=4\\b=16\\c=8\\[/tex]

Then, substituting into the quadratic formula to find the roots of the parabola, we have:

[tex]x=\frac{-b+-\sqrt{b^{2}-4ac } }{2a}\\\\x=\frac{-16+-\sqrt{(16)^{2}-4*4*8 } }{2*4}=\frac{-16+-\sqrt{(256-128) } }{8}\\\\x==\frac{-16+-\sqrt{(256-128) } }{8}=\frac{-16+-\sqrt{(28 } }{8}\\\\x=\frac{-16+-\sqrt{128 } }{8}=\frac{-16+-(11.31) }{8}\\\\\\x_{1}=\frac{-16+(11.31) }{8}=-0.59\\\\x_{1}=\frac{-16-(11.31) }{8}=-3.41[/tex]

Hence,the parabola intercepts the x-axis in two points.

[tex]x_{1}=-0.59\\\\x_{2}=-3.41[/tex]

Answer:

The largest angle is 6x,and 6x=90

So, the measure of the largest angle is 90

Step-by-step explanation:

First, you create an equation by adding the three angles together and equal to 180,because a triangle has 180 degrees.

The result will be 15.If x=15 ,you need to plug it in.

the largest angle is 6x,So, 6.15=90

90 degrees

The problem states the measures of three angles of a triangle as 4x-1, 2x+1, and 6x. According to the basic theorem that the sum of the angles in a triangle is 180 degrees, if we add these angles together, and equate them to 180, we get the equation 4x - 1 + 2x + 1 + 6x = 180. Adding like terms simplifies this to 12x = 180, and dividing each side by 12 gives us x = 15. Therefore, the largest angle is 6x, which would be 6 * 15 = 90 degrees.

Answer:

x= 15/8

Step-by-step explanation:

we need to solve the equation to find the value of x by adding like terms and then finding the value of x.

[tex](\frac{1}{2})x+(\frac{3}{2})(x+1)-(\frac{1}{4})=5\\(\frac{1}{2})x + (\frac{3}{2})x + (\frac{3}{2}) - (\frac{1}{4}) = 5\\Adding\,\,like\,\,terms\,\\(\frac{(1+3)x}{2}) + (\frac{6-1}{4})=5\\(\frac{4x}{2}) + (\frac{5}{4})=5\\2x= 5- \frac{5}{4}\\2x = \frac{20-5}{4}\\2x= \frac{15}{4}\\x= \frac{15}{4*2}\\x= \frac{15}{8}[/tex]

The value of X is ratio of fifteen to eight. That is, x = 15/8

Algebraic equation comprises of unknown variables with equality sign.

To evaluate 1/2x+3/2(x+1)-1/4 = 5, Find the LCM in the left hand side.

[tex]\frac{x}{2}[/tex] + [tex]\frac{3(x+1)}{2}[/tex] - [tex]\frac{1}{4}[/tex] = 5

At the Left hand side, the L.C.M is 4

[tex]\frac{2x+6(x+1)-1 }{4} = 5[/tex]

Cross multiply

2x + 6x + 6 - 1 = 20

8x + 5 = 20

Collect the like terms

8x = 20 - 5

8x = 15

Make x the subject of the formula

x = 15/8

Therefore, x = 15/8 in the given algebraic equation.

Step-by-step explanation:

You need to distribute the 8 to everything in the equation. You need to keep the sign in the middle. So in the end you would get 8x+8y.

Final answer:

Option a), 8x + 8y, accurately represents the total number of erasers Shawn bought since it's obtained by distributing the number of boxes, 8, to both x and y inside the parentheses.

Explanation:

The expression 8(x + y) represents the total number of erasers Shawn bought, where x is the number of pink erasers in each box and y is the number of blue erasers in each box. Since Shawn bought 8 boxes, and each box contains x pink erasers and y blue erasers, we need to multiply the sum of pink and blue erasers in one box by the number of boxes to get the total. Hence, the correct expression that also represents the total number of erasers Shawn bought is option a), 8x + 8y which is obtained by distributing the 8 to both x and y inside the parentheses.

Answer:

150 CASH

Step-by-step explanation:

if you do 25 down and 12 dollar for 11 month you pay 7 more dollars

Final answer:

The cost of financing the smartphone with a down payment and monthly payments would be $157.00, compared to a one-time cash payment of $150.00.

Explanation:

The question posed involves comparing the cost of purchasing a smartphone either with a one-time cash payment or financing it with a down payment followed by monthly payments. To calculate the total cost of the financing option, you add the down payment to the product of the monthly payment amount and the number of months for repayment. In this case, we use the following calculation: $25.00 down payment + ($12.00 per month × 11 months) = $25.00 + $132.00 = $157.00. The total cost when financing the smartphone would be $157.00, which is $7.00 more than the upfront cash payment of $150.00.

Answer:

120 degrees aka answer D

Step-by-step explanation:

Answer:

D. 120°.

Step-by-step explanation:

Since the angle is obtuse (greater than 90), it cannot be 30°, since 30° is an acute angle.

The angle cannot be 90° since the angle is obtuse, and red curved line is not a square.

The line would be straight if the angle was 180°, so the most reasonable answer would be D. 120°.
