Answer:

$10p^2+3p+4$

Step-by-step explanation:

$12p^2-\frac{2}{5} (5p^2-10)+3p\\12p^2-0.4 (5p^2-10)+3p\\12p^2-2p^2+4+3p\\10p^2+3p+44$

The school purchased baseball equipment and uniforms for a total cost of 1762.00. The equipment costs 598 and the uniforms were

Norma-Jean [14]

U= uniforms

598+ 24.25u= 1762

24.25u= 1762- 598

24.25u= 1164

U= 1164/24.25

U= 48

The school purchased 48 uniforms.

Hope this helps!

Trapezoid MNPQ is similar to Trapezoid RSTU. What is the length of the "x" on the misside side NP ? Also, what is the length of

ivolga24 [154]

Answer:

$x = 15$

$y = 25$

Step-by-step explanation:

Given

See attachment for MNPQ and RSTU

Required

Find x and y

To solve this question, we make use of equivalent ratios of corresponding side lengths.

The ratio of corresponding sides are:

$MN : RS$

$NP : ST$

$PQ : TU$

$MQ : RU$

From the attachment, we have:

$MN : RS \to 18 : 30$

$NP : ST \to x : 25$

$PQ : TU \to 15 : y$

To solve for x, we equate $MN : RS$ and $NP : ST$

$18 : 30 = x : 25$

Express as fraction

$\frac{18 }{ 30 }= \frac{x }{ 25}$

Make x the subject

$x = 25 * \frac{18 }{ 30 }$

$x = \frac{25 * 18 }{ 30 }$

$x = \frac{450}{ 30 }$

$x = 15$

To solve for y, we equate $MN : RS$ and $PQ : TU$

$18 : 30 = 15 : y$

Express as fraction

$\frac{18 }{ 30 }= \frac{15 }{ y}$

Make y the subject

$y = 15 * \frac{30 }{ 18 }$

$y = \frac{15 *30}{ 18 }$

$y = \frac{450}{ 18 }$

$y = 25$

How do you find the slope of the line that goes<br> through the points (-5, 6) and (7,-6)?

strojnjashka [21]

Answer:

Step-by-step explanation:

$slope=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\frac{-6-6}{7-[-5]}\\\\=\frac{-12}{7+5}\\\\=\frac{-12}{12}\\\\=-1$

PLEASE HURRY!!! AB = 20 cm, m∠A = 30° , and $m∠C = 45° . Express the number of centimeters in the length of BC in simplest radic

MrRissso [65]

Using the Sine Rule:-

20 /sin 45 = BC / sin 30

BC = 20 sin 30 / sin45

= 20 * 1/2 / 1 / sqrt2
= 20 * 1/2 * sqrt2
= 10 sqrt2 answer
