Scale factors will determine whether a shape is____ or not
Answer:
similar
Step-by-step explanation:
Hope that helps!
Answer:
Scale factors will determine whether a shape is similar or not.
Step-by-step explanation:
Take this sample from
-varsitytutors.com
"The scale factor is the ratio of the length of a side of one figure to the length of the corresponding side of the other figure. Here, XYUV=123=4 . So, the scale factor is 4 . Note that when a two-dimensional figure is enlarged ( dilated ) by a scale factor of k , the area of the figure is changed by a factor of k2 ."

Zoe compares the price of a sweatshirt at two stores. At Store A, the sweatshirt costs $25. A friend told her that the sweatshirt costs 30% more at Store B.
Zoe wrote the expression 25+0.3(25) to find the price of the sweatshirt at Store B.
Which equivalent expression could she also use to find the price of the sweatshirt at Store B?
A) (1+0.3)25
B) (1−0.3)25
C) 1+0.3(25)
D) 25 + 0.3
Answer:
A) (1+0.3)25
Explanation:
Zoe's expression 25+0.3(25) equals to 32.5. So the only expression that equals to 32.5 is A) (1+0.3)25.

Anna is 18. Rita is 13.
13
Mark is 12.
Step-by-step explanation:
Recall that the perimeter of a shape is the sum (or total) of all the edges that make up that shape. So, for the first shape, there are three Xs. We write this as [tex]\bold{3x}[/tex] so this is the perimeter.
In the second, there are four Xs, so this is [tex]\bold{4x}[/tex].
In the third, there are two Xs and two 5s, so this is [tex]2x+(2*5)=\bold{10+2x}[/tex].
In the fourth, there are two Xs and three 4s, so this is [tex]2x+(3*4)=\bold{12+2x}[/tex].
If each is equal to 24, we can simply set them as equal to 24 and solve.
[tex]3x = 24\\\bold{x=8}[/tex]
----
[tex]4x=24\\ \bold{x=6}[/tex]
----
[tex]10+2x=24\\2x = 14\\\bold{x=7}[/tex]
----
[tex]12+2x=24\\2x=12\\\bold{x=6}[/tex]
If Anna is 5 years older than Rita, then [tex]a=r+5[/tex]. If their sum is 31, then [tex]a+r=31[/tex]. We can perform some substitution:
[tex](r+5)+r=31\\5+2r=31\\2r=26\\r=13[/tex]
Therefore, Rita is 13. Keep going:
[tex]a=r+5\\a=13+5\\a=18[/tex]
Anna is 18.
If Dad is three times as old as Mark, then [tex]d=3m[/tex]. If the sum of their ages is 48, then [tex]d+m=48[/tex]. We can perform some algebra:
[tex]d+m=48\\m=48-d\\d=3(48-d)\\d=144-3d\\4d=144\\d=36[/tex]
Dad is 36. Keep going:
[tex]d=3m\\36=3m\\m=12[/tex]
Mark is 12.

In the given polygon, AC= 5x - 24, AO= 3. Find x. NO LINKS!!!
Answer:
[tex]x=6[/tex]
Step-by-step explanation:
5x - 24 = 3 * 2
5x - 24 = 6
5x = 30
x = 6
Answer:
Solution given:
AC= 5x - 24, AO= 3.
now
since diagonal bisect each other So,
AC=2 AO
5x-24=2(3)
5x=6+24
x=30/5
x=6
Find the P-value for a test of the claim that more than 60% of the people following a particular diet will experience increased energy (H1: p > 0.6). Of 100 randomly selected subjects who followed the diet, 70 noticed an increase in their energy level. 2.041 1.5486 1.2743 2.536
Answer:
The p-value of the test is 0.0207.
Step-by-step explanation:
Test of the claim that more than 60% of the people following a particular diet will experience increased energy (H1: p > 0.6).
The null hypothesis is:
[tex]H_0: p = 0.6[/tex]
The alternate hypothesis is:
[tex]H_1: p > 0.6[/tex]
The test statistic is:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
0.6 is tested at the null hypothesis:
This means that [tex]\mu = 0.6, \sigma = \sqrt{0.6*0.4}[/tex]
Of 100 randomly selected subjects who followed the diet, 70 noticed an increase in their energy level.
This means that [tex]n = 100, X = \frac{70}{100} = 0.7[/tex]
Test statistic:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]z = \frac{0.7 - 0.6}{\frac{\\sqrt{0.6*0.4}}{\sqrt{100}}}[/tex]
[tex]z = 2.04[/tex]
P-value of the test:
The p-value of the test is the probability of finding a sample proportion of at least 0.7, which is 1 subtracted by the p-value of z = 2.04.
Looking at the z-table, z = 2.04 has a p-value of 0.9793
1 - 0.9793 = 0.0207
The p-value of the test is 0.0207.

Bill is selling stickers to raise money for a charity. He sold 36 stickers on the first day and 23 on the second day. He had 26 stickers left at the end of the second day. How many stickers did Bill have to start with?
Answer:
85 stickers
Step-by-step explanation:

What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
WE have been given that Bill sold 36 stickers on the first day and 23 on the second day. He had 26 stickers left at the end of the second day.
Then the equation would be;
y - 36 - 23 = 26
y - 59 = 26
Subtract 59 from both the sides;
y - 59 + 59 = 26 + 59
y = 85
Hence, Bill have to start with 85 stickers.
