Answer: the answer is 23

Step-by-step explanation:

Answer:

23

Step-by-step explanation:

10+8+5=23

Answer:

Kindly check attached picture for circle illustration.

Step-by-step explanation:

The whole circle = 1

Half the circle = semicircle = 1/2

Half the semicircle = 1/4

Half of 1/4 = 1/8

Hence, Geraldo would obtain 1/8

Normal calculation:

1/2 ÷ 2

1/2 * 2/1 = 1/4

Quotient = 1/4

Quotient / 2

1/4 ÷ 2

1/4 * 1/2

= 1/ 8

Answer: 1/12 of the whole pizza

Step-by-step explanation:

Someone cut a whole pizza into 3 pieces.

This means that the pizza was cut into 1/3 slices each.

She then gave her 4 children one of these sections to share equally.

The part each child got is:

= 1/3 ÷ 4

= 1/3 * 1/4

= 1/12 of the whole pizza

Note: When dividing fractions, you can multiply the first fraction by the inverse of the second fraction to find your answer.

Answer:

y-intercept of the function [tex]y=\frac{2}{3}x-3[/tex] is -3.

Step-by-step explanation:

We need to find the function that had the same y-intercept as the function [tex]y=\frac{2}{3}x-3[/tex]

(Note: Since the options are not given, so I will find the y-intercept of the given equation and you can match it with the functions and find the y-intercept of the required function)

The equation given [tex]y=\frac{2}{3}x-3[/tex] is written in slope-intercept form i.e [tex]y=mx+b[/tex] where m is slope and b is y-intercept.

Comparing equation [tex]y=\frac{2}{3}x-3[/tex] with [tex]y=mx+b[/tex] we get the value of b = -3

So, y-intercept of the function [tex]y=\frac{2}{3}x-3[/tex] is -3.

Now, for the options (not included) in the question, you can find y-intercept and function that have y-intercept = -3 will be the answer.

Answer:

3(x+y)+15xy

Step-by-step explanation:

Write an algebraic expression for the verbal expression: three times the sum of X and Y increase by five times the product of x and 3y.

Sum of x and y = x+y

three times the sum of X and Y = 3(x+y)

product of x and 3y  = x(3y) = 3xy

five times the product of x and 3y = 5(3xy) = 15xy

Three times the sum of X and Y increase by five times the product of x and 3y will be expressed as;

3(x+y) + 15xy

Hence the required algebraic expression is 3(x+y)+15xy

8/15

Explication étape par étape:

Prendre:

Longueur = x

Largeur = y

Zone du rectangle = Longueur * largeur

Un cinquième de longueur = x / 5

Un tiers de largeur = x / 3

Zone d'origine = xy

Nouvelle dimension:

Longueur = x + x / 5 = (5x + x) / 5 = 6x / 5

Largeur = x + x / 3 = (3y + y) / 3 = 4y / 3

Nouvelle zone = 6x / 5 * 4y / 3

Nouvelle zone = (24/15) xy

Fraction de la nouvelle zone par rapport à la zone d'origine:

(24/15) xy: xy

24/15: 1

24/15

= 8/5

Answer:

C) 5

Step-by-step explanation:

The measure of angle TSU is 75°. (180° - 105° because it is a flat angle)

The sum of all the angles of a triangle is 180° as well.

You can write an equation to solve for x.

12x + 9x + 75 = 180

Isolate x.

12x + 9x = 180 - 75

12x + 9x = 105

Add the 12 and the 9.

21x = 105

Find what x is.

x = 105 ÷ 21

x = 5

Answer:

[tex]4P+2G=96\\3P+1G=60 or 3P+G=60[/tex]

Step-by-step explanation:

Given in the question:

a) A family paid $96 for 4 pool passes and 2 gym memberships.

b) Later that day, an individual bought pool passes for herself and 2 of her friends, and 1 gym membership for her. She paid $60.

Let's write the system of equations for each purchase  that happened in the scenario.

Let,

P=Price of each pool passes

G= Price of each gym membership

We get,

a) A family paid $96 for 4 pool passes and 2 gym memberships:

[tex]4P+2G=96[/tex]

b) Later that day, an individual bought pool passes for herself and 2 of her friends , and 1 gym membership for her. She paid $60:

[tex]3P+1G=60[/tex]

Therefore, the equations generated in the scenario were:

[tex]4P+2G=96\\3P+1G=60 or 3P+G=60[/tex]

Where,

P=Price of each pool passes

G= Price of each gym membership

Given the data from the question, the correct statement is: the ratio 1:5 is less than 3:10

To otain the comparison of both ratios, we shall determine the value of each ratio. This is illustrated below:

1 : 5 = 1 / 5

1 : 5 = 0.2

3 : 10 = 3 / 10

3 : 10 = 0.3

SUMMARY

Thus, we can conclude that 1:5 is less than 3:10

Answer:

y=-2.5[tex]x^{2}[/tex]+4.5x+1.5

Step-by-step explanation:

standard form of equation of parabola is,

y=a[tex]x^{2}[/tex]+bx+c

For x=0

1.5=0a+0b+c

1.5=c

For x=-2,

2.5=4a-2b+c

substituting the value of c

2.5=4a-2b+1.5

on solving,

4a-2b=1____________(1)

For x=4,

-60.5=16a+4b+c

substituting the value of c,

-60.5=16a+4b+1.5

on solving,

16a+4b=-62_______(2)

Multiplying equation 1 by 2,

8a-4b=2_______(3)

adding equation 2 and 3

16a+4b+8a-4b=-62+2

24a=-60

on solving,

a=-2.5

substituting the value of a in equation 1,

10-2b=1

2b=9

b=4.5

hence, equation of parabola in standard form is,

y=-2.5[tex]x^{2}[/tex]+4.5x+1.5

Sara brought a total of 5 cartons of blackberries. Since it said that Sara brought 6 cartons and you know that the cost of the blackberries are $2, you multiply 6 with 2 but its 12. But if Sara  brought 2 cartons of raspberries it will be $3. Now you subtract 6 with 2 since you used 2 cartons on raspberries and now multiply $2 with 4 and get 8. 8+3=11, which is exactly how much she needs. This means that Sara brought 4 cartons of blackberries.
