A portrait without its frame has a height 1.5 times its width w, in inches. Its frame is 2 in wide all along its perimeter what is an expression for
the area of the framed portrait in terms of w?
O A 1.5w2 + 5w + 4
B. 1.5w? + 8w + 8
C
1.5w2 + 8,5W + 16
O
D. 1.5w2 + 10w + 16
Answer:
1.5w² + 10w + 16 sq, inches.
Step-by-step explanation:
The height of the portrait without the frame is 1.5 times its width.
Let the height is 1.5w inches and width is w inches.
Now, the frame around the portrait is 2 inches wide.
So, the dimensions of the portrait with frame are (1.5w + 4) inches by (w + 4) inches.
Therefore, the area of the framed portrait will be
(1.5w + 4)(w + 4)
= 1.5w² + 10w + 16 sq, inches. (Answer)
Dedra is making headband to sell to her friends.Each headbands requires 1 7/8 feets fabric.If dedra plans to make 14 headbands than how much fabric will she need .
Answer:
26.25 feets
Step-by-step explanation:
Given:
Each headbands requires 1 7/8 feets fabric
Dedra has to make 14 headbands .
Question asked:
how much fabric will she need to make 14 headbands = ?
Solution:
By applying unitary method :
Length of fabric require to make a headband = [tex]1\frac{7}{8}[/tex]
= [tex]\frac{15}{8}[/tex]
Length of fabric require to make 14 headbands = [tex]14\times\frac{15}{8}[/tex]
= [tex]\frac{210}{8}[/tex]
= [tex]26.25 feets[/tex]
Therefore, Dedra needs 26.25 feets fabric to make 14 headbands.
8 2/5 - 5 3/5 need help solving step by step
Answer: 2 and 4/5
Explanation: To subtract mixed numbers, first subtract the fractions. Notice here however that we have 2/5 - 3/5 which will give us a negative fraction. Since this will cause us a lot of trouble, instead, let's rewrite the first mixed number.
We can do this by thinking of 8 and 2/5 as 7 + 1 and 2/5 or 7 + 7/5 by changing 1 and 2/5 to the improper fraction 7/5. So 8 and 2/5 can be written as 7 and 7/5.
So we have 7 and 7/5 - 5 and 3/5.
Now, subtract the fractions. So we have 7/5 - 3/5 which is 4/5. Then subtract the whole numbers so we have 8 - 5 which is 2.
2 and 4/5 is in lowest terms so 8 and 2/5 - 5 and 3/5 is 2 and 4/5.
Roman purchased 2 1/2 pounds of
chocolate covered peanuts for $9.75.
What was the price per
pound?
Answer:
$3.90 is the answer.
Step-by-step explanation:
9.75 ÷ 2.5 = 39/10 (3.9).
To check do 3.9 × 2.5 = 9.75.
Final answer:
To determine the price per pound of chocolate covered peanuts, divide the total cost ($9.75) by the total weight (2.5 pounds), resulting in $3.90 per pound.
Explanation:
The question asks to calculate the price per pound of chocolate covered peanuts Roman purchased.
Here is a step-by-step explanation:
First, it is important to take note of the total weight of the chocolate covered peanuts, which is 2 1/2 pounds or 2.5 pounds.
Next, we look at the total price paid for the 2.5 pounds, which is $9.75.
To find the price per pound, divide the total price by the total weight: $9.75 ÷ 2.5 pounds.
The price per pound turns out to be $3.90.
Therefore, the price per pound of the chocolate covered peanuts is $3.90.

10=8h
h=?
Answer: h = 1.25
Step-by-step explanation:
divide 10 by 8 to get 1.25 or 5/4
In this question, you're solving for h.
Solve for h:
10=8h
"h" can't have a number next to it, it has to be by itself, so divide both sides by 8
1.25 = h
Answer:
1.25 = h

Four tomatoes cost $3.40. What is the unit rate?
Answer:
$0.85 per tomato
Step-by-step explanation:
A unit rate is the cost for one item. Like $0.99 for this one bag of skittles.
So $3.40 divided by four is $0.85.
The unit rate would be 0.85. If you divide 3.40 by 4 you 0.85
AB= 7x-6 BC= 12-2x B is the midpoint of AC. Find AB
Answer:
8
Step-by-step explanation:
set 7x-6 = 12-2x because midpoint segments are equal to each other than solve
9x-6=12
9x=18
x=2
then substitute in values.
B is the midpoint of AC. Using this information, we can set up an equation to solve for AB. After solving for x, we substitute the value back into the equation to find AB. The length of AB is 8 units.
Explanation:We are given that B is the midpoint of AC. This means that the lengths AB and BC are equal. We can set up an equation to solve for AB.
AB = BC
7x-6 = 12-2x
Now we can solve for x and then find AB.
Bring like terms together:
7x + 2x = 12 + 6
9x = 18
Divide both sides by 9:
x = 2
Now substitute the value of x back into the equation for AB:
AB = 7(2) - 6
AB = 14 - 6
AB = 8
Therefore, AB is equal to 8 units.

at a currency exchange,8 u.s dollars can be exchanged for 6 euros. how many euros will you receive for 1 u.s dollar
You will receive 0.75 euros for 1 U.S dollar.
Explanation:In this currency exchange, you receive 6 euros for every 8 U.S dollars. To find out how many euros you will receive for 1 U.S dollar, you can set up a proportion.
Let x represent the number of euros you will receive for 1 U.S dollar. The proportion can be set up as follows: 8 U.S dollars / 6 euros = 1 U.S dollar / x euros.
Now, cross-multiply and solve for x: 8x = 6 * 1. Divide both sides by 8 to isolate x, and you will find that x = 0.75 euros.

if angles of a triangle are 2 is to 3 is to 4 is to .find the value of each angle
Answer:
Angles of triangle are 40°,60° and 80°.
Step-by-step explanation:
Given:
if angles of a triangle are 2 is to 3 is to 4.
Let the common factor between the angles be 'x'.
So we can say that;
Angle 1 = [tex]2x[/tex]
Angle 2 = [tex]3x[/tex]
Angle 3 = [tex]4x[/tex]
We need to find the value of each angle.
Solution:
Now we know that;
"Sum of all angles of triangle is 180°."
framing in equation form we get;
[tex]Angle \ 1+Angle\ 2+Angle \ 3 =180[/tex]
Substituting the values we get;
[tex]2x+3x+4x=180\\\\9x=180[/tex]
Dividing both side by 9 we get;
[tex]\frac{9x}{9}=\frac{180}{9}\\\\x=20[/tex]
Angle 1 = [tex]2x=2\times20=40\°[/tex].
Angle 2 = [tex]3x=3\times20=60\°[/tex]
Angle 3 = [tex]4x=4\times20=80\°[/tex]
Hence Angles of triangle are 40°,60° and 80°.

HELP!!! A cell phone is 132 mm long and 57 mm wide. What is ratio of the width and length in simplest form.
The ratio of width to length in simplest form is 19 : 44
Solution:
Given that, A cell phone is 132 mm long and 57 mm wide
Length of cell phone = 132 mm
Width of cell phone = 57 mm
We have to find the ratio of width and length in simplest form
[tex]\frac{Width}{Length} = \frac{57}{132}\\\\\text{Reduce to lowest terms }\\\\\frac{width}{length} = \frac{57 \div 3}{132 \div 3}\\\\\frac{Width}{Length} = \frac{19}{44}[/tex]
In ratio form, we know that,
[tex]\frac{a}{b} = a : b[/tex]
Writing in ratio form, we get
Width : length = 19 : 44
Thus the ratio of width to length in simplest form is 19 : 44

Which function represents g(x), a reflection of f(x)=4(1/2)^x
across the x-axis?
Answer:
[tex]g(x)=-4(\frac{1}{2})^x[/tex]
Step-by-step explanation:
Given:
The parent function is given as:
[tex]f(x)=4(\frac{1}{2})^x[/tex]
The function [tex]g(x)[/tex] is a reflection of the parent function about the x-axis.
Now, in order to find the function g(x), we need to use the rules of function transformations.
As per transformation rules, when a function is reflected about the x-axis, the function rule is given as:
[tex]f(x)\to-f(x)[/tex]
So, the new function or the reflected function is the negative of the original function.
Therefore, the reflected function [tex]g(x)[/tex] is given as:
[tex]g(x)=-f(x)\\\\g(x)=-4(\frac{1}{2})^x[/tex]
Hence, the function that represents the reflection of the given function across the x-axis is [tex]g(x)=-4(\frac{1}{2})^x[/tex]
What is a point slope equation of the line with slope - 13 that goes through
the point (5,7)?
O A. y+7=-13(x+5)
O BY+5=-13(x+ 7)
OG 1-7=-13(x - 5)
O D. y-5=-13(x-7)
Answer:
C. y - 7 = -13(x - 5)
Step-by-step explanation:
The point-slope equation for a straight line is
y - y₁ = m(x - x₁)
where m is the slope and(x₁, y₁) is a point on the line.
If m = -13 and (5, 7) is the point, the equation is
y - 7 = -13(x - 5)
