Can someone help with number 28 and explain how todo it

Answer:

158

Step-by-step explanation:

The Formula for Area is: A = L * W

First lets start with the rechtangle:

A = L * W

A = 17 * 7 = 119

the area of the rechtangle is 119

Now the triangle the formula is a little diffrent but it is the same concept

A=hbb (Picture below, it wont let me write it out right)

2=6·13

2=39

The area of the triangle is 39

Now add the both areas

119 + 39 =

158

Answer:

18 is 30% of 60

Step-by-step explanation:

Try to line up percents % and the actual numbers they represent.

number : precent

       60  is 100%

        18  is x %

cross multiply

x·60 = 100·18

divide both sides by 60 to isolate x

x = ((100·18)/60

x = 30

Answer:

406.08

Step-by-step explanation:

First FInd the area of the rectangle : which is short side * long side

-> 15*12=180m

Then find the area of the half circle, the formula of the area of a circle is [tex]\pi r^2[/tex]

here it's half a circle so it's [tex]\frac{\pi r^2}{2}[/tex] where r is 12

-> [tex]3.14\cdot \frac{\left(12\right)^2}{2}=226.08 m[/tex]

Finally just add the area of the rectangle with the area of the half circle

-> [tex]180+226.08=406.08 m[/tex]

Answer:

13x9

Step-by-step explanation:

half of perimeret of  rectangle L+W

half of perimeter of  rectangle = 44/2 = 22

L+W=22

LxW=117

  Think of 2 numbers that added =22 and multiplied =117

       13+9 =22

    13x9 =117

Step-by-step explanation:

The predicted strength is an illustration of a linear regression

The predicted strength of a weld with a diameter of 51 is -503.2

The equation of the predicted strength is given as:

Strength = -941.6992 + 8.5988*Diameter

Substitute 51 for diameter

Strength = -941.6992 + 8.5988*51

Evaluate the sum

Strength = -503.1604

Approximate

Strength = -503.2

Hence, the predicted strength of a weld with a diameter of 51 is -503.2

The predicted strength is an illustration of linear regression.

The predicted strength of a weld with a diameter of 51 is -503.2.

Linear regression strives to show the relationship between two variables by applying a linear equation to observed data.

The equation of the predicted strength is given as:

Strength = -941.6992 + 8.5988 × Diameter

Substitute 51 for diameter

Strength = -941.6992 + 8.5988 × 51

Strength = -941.6992 + 438.5898

Strength = -503.1604

Strength = -503.2

Hence, the predicted strength of a weld with a diameter of 51 is -503.2.

Answer:

The Scale Factor is 5.3

Step-by-step explanation:

Here's the reason why:

You are trying to make the rectangle much larger.

The 14yd by 6yd is trying to get to the 74.2yd by 31.8yd.

We need to remember the importance of length and width.

If 14 yards is our length then 74.2 yards is our length on the enlarged rectangle.

You must do 74.2/14 because we need to work backwords.

**You can't find something to multiply 14 by to get to 74.2 unless you do division.**

74.2/14 is 5.3

Now do the same with the width.

31.8/6

That is 5.3 as well.

Therefore the scale factor is 5.3

This is the answer. If this helps you please give brainliest.

Work Shown:

[tex]\frac{2^x \times 3^y}{2^4 \times 3^2} = 6\\\\\frac{2^x \times 3^y}{2^4 \times 3^2} = 2\times3\\\\\frac{2^x \times 3^y}{2^4 \times 3^2} = 2^1\times3^1\\\\2^x \times 3^y = (2^4 \times 3^2)(2^1\times 3^1)\\\\2^x \times 3^y = (2^4\times2^1) (3^2\times 3^1)\\\\2^x \times 3^y = 2^{4+1} \times 3^{2+1}\\\\2^x \times 3^y = 2^{5} \times 3^{3}\\\\[/tex]

The 2^x matches with 2^5, showing that x = 5.

3^y matches with 3^3 to get y = 3

Therefore, x+y = 5+3 = 8

Step-by-step explanation:

Answer:

yes

Step-by-step explanation:

Using the Pythagorean Theorem, considering that the sum of the squares of the lengths of the two smaller sides is equals to the square of the length of the greater side, the triangle is a right triangle.

Pythagorean Theorem:

The Pythagorean Theorem states that for a right triangle, the sum of the squares of the lengths of the two smaller sides is equals to the square of the length of the greater side.

so it is a right triangle.

Step-by-step explanation:

Answer:

(0,4)

it was correct

Using proportions, it is found that the cost of each banana is of $0.59, and Juan is the student who wrote and solved the equation correctly.

A proportion is a fraction of a total amount.

In this problem, the cost of 4 bananas is $2.36, hence the cost of each banana is given by:

C = $2.36/4 = $0.59.

Which means that Juan is correct.

Answer:

52.

Step-by-step explanation:

shaded = (3²) + (2²)

shaded = 9 + 4

shaded = 13

Unshaded = (3 x 2) + (2 x 3)

Unshaded = 6 + 6

Unshaded = 12

All = 12 + 13

All = 25

100 / 25 = 4

4 x 13 = 26 x 2

26 x 2 = 52.
