Answer:
7. x = 88
8. x = 59
Step-by-step explanation:
You're probably trying to equal 180° because that's what the triangle should equal so
7. 48° + (88° - 44°) + 88° = 180°
8. 73° + (59° - 11°) + 59° = 180°
I hope this is right :,)
X=8
For #8:
X=59

Eduardo has a recipe that uses 2/3 cup of flour for each batch. If he makes 4 batches, how many cups of flour will he need? How many cups of flour will he need in total if he makes 3 more batches?
Answers
Answer:
4 batches: [tex]2\frac{2}{3}[/tex] cups
7 batches: [tex]4\frac{2}{3}[/tex] cups
Step-by-step explanation:
If he uses 2/3 cup of flour for each batch, then that is 2/3 four times, or 2/3 · 4.
[tex]\frac{2}{3}[/tex] × [tex]\frac{4}{1}[/tex]
= [tex]\frac{8}{3}[/tex] = [tex]2\frac{2}{3}[/tex]
If he makes three more, than that will be 7 batches in total. We can multiply 2/3 by 3 to find out how much will be needed for those extra three, then add that product to [tex]2\frac{2}{3}[/tex].
[tex]\frac{2}{3}[/tex] × [tex]\frac{3}{1}[/tex]
= [tex]\frac{6}{3}[/tex] = 2
[tex]2\frac{2}{3} +2[/tex] = [tex]4\frac{2}{3}[/tex]
Thus, [tex]2\frac{2}{3}[/tex] and [tex]4\frac{2}{3}[/tex] are the answers.

The only answer that would result in a non-congruent triangle would be Option 1. It is asking you to dilate by a scale factor of 2 which would make the triangle 2 times bigger. In that case, the triangle to not be congruent.
Reflections, Rotations, and Translations do not change the size of the triangle which means it remains congruent.

In the question we're provided with an equation that is :
v/7 = 3And we are asked to find the solution for the equation .
Solution : -
[tex] \longrightarrow \: \frac{v}{7} = 3[/tex]
Multiplying by 7 on both sides :

Answers
Answer:
500 calories an hour are burnt.
Step-by-step explanation:
45 is 3/4 of 60, so 375 is 3/4 of an hour of jogging. If we divide 375 by 3 we will get how many calories are burnt every 1/4 of an hour.
375 / 3 = 125
Now that we know what 1/4 of an hour equals we can add 125, 4 times to find the number of burnt calories in an hour of running.
125 + 125 + 125 + 125 = 500
that means jogging burns 500 calories an hour.
Two prisms are similar and their ratio of similarity is 2:5.
Find the area of a base of the larger prism if the area of a base of the smaller prism is 31 square units.
Round to the nearest hundredth.
help fast please
Answers
Answer:
77.5 square units
Step-by-step explanation:
set up a proportion first.
[tex] \frac{2}{5} = \frac{31}{x} [/tex]
then, cross multiply
2x = 155
divide by 2
x = 77.5
The area of the base of the larger prism is approximately 193.75 square units.
How to calculate the area?If two prisms are similar, then their corresponding sides are proportional. Let the smaller prism have a base area of 31 square units, and let the corresponding side of the larger prism have length x.
Since the ratio of similarity is 2:5, we have:
x / s = 5/2
where s is the length of the corresponding side of the smaller prism. Solving for x, we get:
x = (5/2) x s
We know that the area of the base of a prism is given by the formula:
A = s²
Substituting the value of s in terms of x, we get:
A = ((5/2) x s)²
A = (25/4) x s²
Substituting the value of s² in terms of the area of the smaller prism, we get:
A = (25/4) x 31
A = 775/4
A = 193.75 square units
Therefore, the area of the base of the larger prism is approximately 193.75 square units.

The approximate difference in their volumes is 17.2 cubic inches
Volume of a sphereA sphere is a round solid figure, with every point on its surface equidistant from its centre.
The formula for calculating the volume of a sphere is;
V = 4/3πr³
where:
r is the radius of the sphere
Given the following
diameter of youth ball =2.8in
radius of youth ball r = 1.4in
diameter of adult ball =3.8in
radius of adult ball R = 1.9in
Determine the difference in volume
D = 4/3π(R³ - r³)
Substitute
D = 4/3π(1.9³ - 1.4³)
D = 4/3π(4.115)
D =17.2 cubic inches
