Answer:7 3/5

Step-by-step explanation: 3 4/5 blueberries = 2 2/3 strawberries

                                               ? blueberries    =5 1/3 strawberries

do 3 4/5 times 5 1/3 which gives you 20 4/15.Now divide 20 4/15 by 2 2/3 which gives you 7 72/120 and you can simplify to 7 3/5.

Hope it helps  . :)

Step-by-step explanation:

It sounds like you are asked to estimate it. That's a very valuable skill.

9.634 is about 10

445.76 is about 446

So an approximate answer is 446 * 10 = 4460

How close is that to the actual answer? Let's find out.4294.45

On a test, if you get an answer like 4460 in your head, and your calculator says 4294.45, you are pretty certain that you have done the question correctly.

Answer:

Step-by-step explanation:

= 4+8/2×(6-3)

= 12/2×6-2×3

= 12/12-6

= 12/6

= 2

Slope of BC = AB/AC, and Slope of EF = DE/DF

BC and EF both lie on the same line t, therefore the slope of BC equals the slope of EF.

Similar triangles are two triangles having the same shape but different sizes, however, the ratio of their corresponding sides are equal.

Given:

ΔABC ~ ΔDEF

Slope of BC = AB/AC

Slope of EF = DE/DF

BC and EF both lie on the same line t, therefore the slope of BC equals the slope of EF.

Answer:

2,112 ft³

Step-by-step explanation:

Volume of composite solid = volume of pyramid + volume of cube

✔️Volume of square pyramid = ⅓(a²)*h

Where,

a = 12 ft

h = 8 ft

Plug in the values

Volume of pyramid = ⅓(12²)*8 = 384 ft³

✔️Volume of cube = a³

Where,

a = 12 ft

Plug in the value

Volume of cube = 1728 ft³

✔️Volume of composite solid = 384 + 1728 = 2,112 ft³

Answer:

hmm ..

just transfer the X at the right side and others on left side

Step-by-step explanation:

so you get

w-z = yx

so later

(w-z)/y = x

The required value of x for the equation w - yx = z  is (w - z)/y.

An equation is a combination of different variables, in which two mathematical expressions are equal to each other.

The given equation is,

w - yx = z

Solve to determine the value of x,

Subtract w from both the sides,

w - yx - w = z - w

-yx = z - w

Multiply with -1 both the sides,

yx = w - z

⇒x = (w - z)/y

The value of x for the given equation is (w - z)/y.

Answer:

x = 34.06

Step-by-step explanation:

The sum of angles in the triangle LUV is 180 degrees

Given

∠L=(3x+y)°

∠U=42.6°

∠V=(4x−3y−0.8)°

Since ∠L+∠U + ∠V = 180 degrees

Substitute:

3x+y + 42.6 + 4x - 3y - 0.8 = 180

7x - 2y - 41.8 = 180

7x - 2y = 221.8 ... 1

Since UV = UL, hence the triangle is isosceles and <V = <L

3x+y = 4x-3y - 0.8

-x +4y = -0.8

x  - 4y = 0.8 ....2

From 2: x = 0.8+4y

Substitute into 1:

7x - 2y = 221.8

7(0.8+4y) - 2y = 221.8

5.6 + 28y-2y = 221.8

26y = 221.8-5.6

26y = 216.2

y = 8.32

Get x

x = 0.8+4y

x = 0.8+4(8.32)

x = 0.8 + 33.26

x = 34.06

Note that it was assumed that <V = <l since the question is not clear

Answer:

To solve the problems in this lesson, students use the slope formula, which states that m = (y2 -- y1) / (x2 -- x1). The slope formula can be read as "slope equals the second y coordinate minus the first y-coordinate over the second x-coordinate minus the first x-coordinate".

Step-by-step explanation:

Lindsey had 400 tarts to start with, then she sold off 3/5 of them. Hence find the number of tarts left (2/5 of the original amount). Then she sold 1/4 of the remaining tarts. Therefore, find 1/4 or 2/5 of 400. The equation would be;

[tex](\frac{1}{4})(\frac{2}{5})(400)[/tex]

Step-by-step explanation:

Since the 2 angles are supplementary,

(7x + 5°) + 28x = 180°.

=> 35x + 5° = 180°

=> 35x = 175°

=> x = 5°.

Hence Angle A = 7(5°) + 5° = 40°.
