Answer:

26 is the hypotenuse

Step-by-step explanation:

a² + b² = c²

Given:

a = 24

b = 10

Work:

a² + b² = c²

24² + 10² = c²

576 + 100 = c²

c² = 676

[tex]\sqrt{c^2} =\sqrt{676}[/tex]

c = 26

Answer:

Solution given:

by using Pythagoras law

hypotenuse ²=perpendicular ²+base².

hypotenuse ²=10²+24²

hypotenuse=√676=26

so

hypotenuse=26

Answer:

120cm2

Step-by-step explanation:

6 x 8 = 48cm2

8 x 9 = 72cm2

48 + 72 = 120cm2

Answer:

120 m^2

Step-by-step explanation:

The box on the left is 6m x 8m, thus the area would be 48 m^2.

The box on the right is 9m x 8m, thus the area would be 72 m^2.

Adding both areas would give you the total area of 120 m^2.

Answer:

6:12 = 20:40

Step-by-step explanation:

[tex]\frac{6}{12} =\frac{20}{y}[/tex]

6:12 = 20:y

Cross multiply.

6 × y = 12 × 20

6y = 240

6y ÷ 6 = 240 ÷ 6

y = 40

Answer:

c. 84   if wrong its 72 because im not sure if its esimated but if not its right.

Step-by-step explanation:

42x4.5=189

18x4.5=81

=270

84 of those seventh-grade students would you expect to be left-handed.

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

here, have,

from 60 students ,

left handed = 18

now, from 280 students,

left handed = 280/60*18

                   =84

hence, 84 of those seventh-grade students would you expect to be left-handed.

I don't know how to explain lol

Answer:

22608cm³

Step-by-step explanation:

Step 1

We find how many liters of water can be contained in 1 cup. We do this by finding the volume of the cup.

Cup is shaped as a cone

The volume of a cone = πr²h/3

Where

r = radius = 4cm

h = height = 9cm

π = 3.14

Hence,

Volume of the cone (cup) =

3.14 × 4² × 9/3

= 150.72 cm³

Step 1

How much water is needed to fill 150 cups?

1 cup = 150.72 cm³ of water

150 cups = x

Cross Multiply

x = 150 × 150.72 cm³

x = 22608 cm³ of water

Therefore, 22608cm³ of water is needed to fill 150 cups

Answer:

x = 21, ∠ ABE = 55°

Step-by-step explanation:

∠ ABD is right and

∠ ABE + ∠ DBE = ∠ ABD , that is

3x - 8 + x + 14 = 90

4x + 6 = 90 ( subtract 6 from both sides )

4x = 84 ( divide both sides by 4 )

x = 21

Then

∠ ABE = 3x - 8 = 3(21) - 8 = 63 - 8 = 55°

yo i do primavara to imma do 3.9

Step-by-step explanation:

oh and also if your grades are bad just do to the dashboard page and highlight you grade percentedge and click inspect if you know and if you see you number pecent on the inspect and right click and click edit as htl and change it to any percent you want then just click out of the inspec option and you will have A S AND B S

The approximate length of the cylinder's radius will be 3.3 inches. Then the correct option is A.

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

The longest straw that can fit inside a 5-inch cylindrical cup, if the straw is placed at an angle in the cup, is 6 inches.

Then the approximate length of the cylinder's radius will be given by the Pythagoras theorem.

Let x be the length of the radius. Then we have

x² = 6² - 5²

x² = 36 - 25

x² = 11

 x = √11

 x = 3.316

 x ≅ 3.3

Answer:

15

Step-by-step explanation:

The parallel lines divide the transversals proportionally.

The green length = 24 - c , then

[tex]\frac{24-c}{20}[/tex] = [tex]\frac{c}{12}[/tex] ( cross- multiply )

12(24 - c) = 20c ← distribute left side

288 - 12c = 20c ( add 12c to both sides )

288 = 32c ( divide both sides by 32 )

9 = c

Then

green length = 24 - 9 = 15

Answer:

Step-by-step explanation:

firstly ,

Given That

principal(p)=$2800

Rate(R)=4.25%

Time(T)=30 years

now , we have from formula

simple interest (S.I)=   P × T ×R / 100

    =   (2800×30×4.25)    /   100

    =  $3570  

Therefore , Simple Interest in 30 years will be $3570

now , we know

Amount(A) =  Principal (P) + Interest (I)

                 =    $2800 + $3570

                   = $ 6370

Therefore the simple interest in 30 years will be $3570 and the total amount in the bank will be $6370 .

Use the distributive property to evaluate the expression 5(2x – 3) when x = 2. 5(2x ...

Step-by-step explanation:

answer:

x=10

step-by-step explanation:

let us solve your equation step-by-step

5+2x=25

step 1: simplify both sides of the equation

2x+5=25

step 2: subtract 5 from both sides

2x+5−5=25−5

2x=20

step 3: divide both sides by 29

2x/2=20/2

x=10

Answer:

base = 2

Step-by-step explanation:

area = 1/2 base * height

7 = 1/2b * 7

7 = 7b/2

cross multiply

14 = 7b

divide both sides by 7

b = 2

Answer:

2

Step-by-step explanation:

So the formula for area of a right triangle is A=B*L*1/2

Variables to remember:

H=height

B=base

A=area

We know that 7=7*B* 1/2. Since they say area is 7, height is 7.

So, we know that L has to equal 1 to make 7*B=7

However, we must remember that this is *1/2. So to make area=7, we must get 14. To get 14, we must have 7*2*1/2, which would equal 14*1/2, equaling 7.

So the answer for B is:

2

Answer:

Step-by-step explanation:

to find ∠QPS   we need the arc SQ  and RS   we will take  1/2(RS-QS) = QPS

find QS :

360 = RS + RQ + QS

360 = 150 + 110 + QS

100 = QS  

now plug into formula above

∠QPS = 1/2(150-100)

∠QPS = 1/2(50)

∠QPS = 25°
