Answer:

Cant answer

Step-by-step explanation:

Depending on the option choices and without seeing the option choices I can give you an idea of how to solve this.

Using y=mx+b we can find the y intercept by knowing that B is the value of the y Intercept

NEED HELP ASAP

KengaRu [80]

Answer:

Part 1) Triangle GHI, JKL

Part 2) $(40*15)and(8*3)$ , $(18*6)and(4.5*1.5)$

Step-by-step explanation:

we know that

If two figures are similar

then

the ratio of their corresponding sides are equal and is called the scale factor

Part 1)

case a) triangle GHI

If ABC and GHI are similar

then

$\frac{4}{24}=\frac{3}{7}=\frac{5}{25}$

but

$0.17 \neq 0.43 \neq \ 0.20$

therefore

Triangle GHI is not similar to triangle ABC

case b) triangle DEF

If ABC and DEF are similar

then

$\frac{4}{44}=\frac{3}{33}=\frac{5}{55}$

$0.09=0.09=0.09$

therefore

Triangle DEF is similar to triangle ABC

case c) triangle MNO

If ABC and MNO are similar

then

$\frac{4}{10}=\frac{3}{7.5}=\frac{5}{12.5}$

$0.4=0.4=0.4$

therefore

Triangle MNO is similar to triangle ABC

case d) triangle JKL

If ABC and JKL are similar

then

$\frac{4}{21}=\frac{3}{20}=\frac{5}{29}$

$0.19 \neq 0.15 \neq 0.17$

therefore

Triangle JKL is not similar to triangle ABC

Part 2)

case a) If the rectangles are similar, then

$\frac{40}{8}=\frac{15}{3}$

$5=5$

therefore

the rectangles are similar

case b) If the rectangles are similar, then

$\frac{18}{4.5}=\frac{6}{1.5}$

$4=4$

therefore

the rectangles are similar

case c) If the rectangles are similar, then

$\frac{1,225}{3.5}=\frac{144}{1.2}$

$350\neq120$

therefore

the rectangles are not similar

case d) If the rectangles are similar, then

$\frac{13}{5.2}=\frac{5}{2.5}$

$2.5\neq 2$

therefore

the rectangles are not similar

A recipe calls for 1 1/2 cups of flour, 3/4 cup of white sugar, and 1/8 cup of brown sugar. Which of the following mixing bowls

Lady_Fox [76]

Answer:

So if I'm going to add this numbers i need them to share a denominator

1 1/2 = 1 4/8 1/8 stays the same 3/4 - 6/8 6/8 + 1/8 = 7/8

7/8 + 1 4/8 = 1 11/8 = 2 3/8 so 3 cups would be the best estimate because the 3/8's are important for the exact mesurement

Hope this helps : )
