Answer:

8 kiwi

Step-by-step explanation:

This is a typical proportional problem for Algebra.

You can do this problem several ways, some shorter than others, however, I want you to understand. So, with that said,

You place the following equation together:

Number of Kiwi/Dollars = Number of Kiwi/Dollars

You are given three of the values:

32 Kiwi/16 = x/4 Please notice: You know Jasmine bought 32 Kiwi for $16.00 and know she has $4.00. You do not know how many kiwi she can purchase. Do you see this?

Now, since this is an equation (an equal sign between two fractions) you can cross-multiply. When you do so you multiply the numerator on the left with the denominator on the right. Then cross-multiply the denominator from the left with the numerator on the right.

You are left with the following due to cross multiplication:

16 x = 4 (32) or 128

16x = 128 Solve for x by dividing 16 into 128 and you arrive at 8

WHY I do this problem in this manner is because you can ALWAYS check your work. In other words, plug 8 (the value for x) into the original equation. When you do so watch what happens:

Original equation: 32/16 = x/4

Then:

32/16 = x/4 or 32/16 = 8/4

Cross multiply: Does 32 times 4 equal 16 times 8? Yes, it indeed does.

SOLUTION

From the question given the following statements to prove are correct, then the last part

$\Delta RSU\cong\Delta TSV$

The reason is Side-side-side triangle theorem

This theorem states that all three sides of a triangle are congruent (identical) to the corresponding sides of another triangle, then the triangles themselves are also congruent.

Hence the answer is Side-side-side triangle theorem

Idk wat to do..... ........

Answer:

Mean : 95

Median : 85

Mode : 90

Part B : Impossible

Step-by-step explanation:

We can make an equation to find the mean using the first 5 history test scores.

$85=\frac{80+75+90+75+95+n}{6} \\ \\ 85=\frac{415+n}{6} \\ \\ 510=415+n \\ \\ n=95$

So a 95 would be needed to have a mean of 85.

Next, the median.

First, we sort the first 5 history scores from least to greatest.

We get 75, 75, 80, 90, 95.

Since, 80 is the middle value, it will be used in the calculation of the median.

We can make an equation with this.

$82.5=\frac{80+n}{2} \\ \\ 165=80+n \\ \\ n=85$

So a score a 85 would be needed to have a median of 82.5

Thirdly, the mode.

Since 90 is already in the set once, we can just have Maliah score another 90 to make 90 the mode (with the exception of 75 of course).

Finally, Part B.

We can use the equation we had for the first mean calculation but change 85 to 90.

$90=\frac{80+75+90+75+95+n}{6} \\ \\ 90=\frac{415+n}{6} \\ \\ 540=415+n \\ \\ n=125$

So Maliah would need a score of 125 to make her mean score 90, but since the range is only from 0-100, it is impossible.

A jar can hold of a pound of flour. Austin empties of a pound of flour into the jar. What fraction of the jar is filled? Enter y

11111nata11111 [884]

Answer:

2/3 of the jar was filled with flour

Step-by-step explanation:

The question is incomplete. Here is the complete question.

A jar can hold 3/4 of a pound of flour. Austin empties 1/2 of a pound of flour into the jar. What fraction of the jar is filled? Enter your answer in numerical form.

Given

Amount a jar can hold a = 3/4 of a pound of flour

If Austin empties 1/2 of a pound of flour into the jar, then the amount emptied into the jar b = 1/2 pounds

Fraction of jar filled will be expressed as b/a as shown;

b/a = (1/2)/(3/4)

b/a = 1/2 ÷ 3/4

b/a = 1/2 * 4/3

b/a = 4/6

Simplify to the lowest term

a/b = 2*2/2*3

a/b = 2/3

Hence 2/3 of the jar was filled with flour
