Answer:

∠C = 28°     (as you have done)

AB = 4.7

BC = 8.8

Step-by-step explanation:

cos 62° = AB/10

0.4695 = AB/10

AB = 10(0.4695) = 4.69

sin 62° = BC/10

0.8829 = BC/10

BC = 10(0.8829) = 8.83

Answer:

Number of special bagel sandwiches = 37

Step-by-step explanation:

Let [tex]x,y[/tex] denote number of special bagel sandwiches and plain bagels respectively.

The bagel shop sold 100 items.

[tex]x+y=100\\y=100-x[/tex]

Also, The bagel shop made $385.

[tex]7x+2y=385[/tex]

Put [tex]y=100-x[/tex] in [tex]7x+2y=385[/tex]

[tex]7x+2(100-x)=385\\7x+200-2x=385\\5x=385-200\\5x=185\\x=\frac{185}{5}\\x=37[/tex]

So,

Number of special bagel sandwiches = 37

Answer:

see explanation

Step-by-step explanation:

sum the parts of the ratio, 5 + 6 + 3 = 14 parts

Divide number of members by 14 to find the value of one part of the ratio.

560 ÷ 14 = 40 ← value of 1 part of the ratio

(i)

number of women = 6 × 40 = 240

(ii)

number of children = 3 × 40 = 120

Answer:-3x-21

Step-by-step explanation: use the distributive property

Answer:

y = 2

Step-by-step explanation:

Given

[tex]\sqrt[3]{3y+2}[/tex] + 4 = 6 ( subtract 4 from both sides )

[tex]\sqrt[3]{3y+2}[/tex] = 2 ( cube both sides )

3y + 2 = 2³ = 8 ( subtract 2 from both sides )

3y = 6 ( divide both sides by 3 )

y = 2

Answer:

C

Step-by-step explanation:

consistently goes down by 3.2 for the y value

Complete question :

Lewis walked 8/10 of a mile. Todd walked 3/4 of the way with Lewis. How many miles did Todd walk with Lewis? Show your work.

Answer:

0.6 miles

Step-by-step explanation:

Miles walked by Lewis = 8/10 miles

Miles Todd walked with Lewis = 3/4 of the way

This means : Multiplying the fraction Lewis walked with the fraction Todd walked with Lewis

8/10 * 3/4 = 24/40 = 0.6 miles

Hence, Todd walked 0.6 miles with Lewis

Id say its option 3.

Answer:

A = 140

Step-by-step explanation:

Area of a triangle:

A = 1/2bh

Given:

b = 20

h = 14

Work:

A = 1/2bh

A = 1/2(20)(14)

A = 10(14)

A = 140

Answer:

q= 49.5

Step-by-step explanation:

[tex] \frac{33}{q} = \frac{8}{12} [/tex]

Cross multiply:

8q= 33(12)

8q= 396

Divide by 8 on both sides:

q= 396 ÷8

q= 49.5

Answer:

The base and height of three parallelograms with the same area as the 12 square inches rectangle are

1) First parallelogram;

Base length of parallelogram = 4 units

Height of parallelogram, = 3 units

2) Second parallelogram

Base length of parallelogram = 6 units

Height of parallelogram, = 2 units

3) Third parallelogram

Base length of parallelogram = 5 units

Height of parallelogram, = 2.4 units

Step-by-step explanation:

The vertices of the rectangle are; (0, 0), (4, 0), (4, 3), and (0, 3)

Let ABCD represent the vertices of the rectangle such that we have;

A(0, 0), B(4, 0), C(4, 3), and D(0, 3)

The area of the rectangle, A = The length of AB × The length of CB

The length of AB = √((4 - 0)² + (0 - 0)²) = 4

The length of CB = √((4 - 4)² + (3 - 0)²) = 3

∴ The area of the rectangle, A = 4 × 3 = 12 square units

The area of a parallelogram = Base length × Height

The base and height of three parallelograms with the same area as the 12 square inches rectangle are;

1) Base length of parallelogram = 4 units

Height of parallelogram, = 3 units

The area of the parallelogram, A = Base × Height;

∴ A = 4 units × 3 units = 12 units²

2) Base length of parallelogram = 6 units

Height of parallelogram, = 2 units

The area of the parallelogram, A = Base × Height;

∴ A = 6 units × 2 units = 12 units²

3) Base length of parallelogram = 5 units

Height of parallelogram, = 2.4 units

The area of the parallelogram, A = Base × Height;

∴ A = 5 units × 2.5 units = 12 units².

Answer:

the answer is $880.200

Step-by-step explanation:

Answer:

it should be D/120

Step-by-step explanation:

An example of the box is:

5 the width

3 the length

1 the height.

That would be 5 x 3 x 1.

To double them, you must multiply each number by 2:

5 x 2 = 10

3 x 2 = 6

1 x 2 = 2.

Now the equation is 10 x 6 x 2.

First multiply 10 x 6 (60).

Then 60 x 2 (120).

120 is the answer

Answer:

order pair (2,1) is the solution to the inequality.

Answer:

A) 15x > 45

Step-by-step explanation:

Let X represent an hour. His wage will be 15 times that, so you have:

15x

He needs to earn more than 45 a day, so the inequality needs to be >45

Only answer that satisfies these conditions is A:

A) 15x > 45

Answer:     A.

Step-by-step explanation:

Answer:

its b

Step-by-step explanation:

Well the easy way to find this is to just solve the first one. the equation is

x-y>5 so you plug in the coordinate and you end up with 7-2>5 which is false. So any answer with option one is out and b is the only one that fits that description.
