Mathematics
1 answer:
salantis [7]3 years ago
8 0

Answer:

-60 3/4m

Step-by-step explanation:

The diver first dives down 50 1/4m, which is represented by the -50 1/4m. He then descends another 10 1/2m down. So -50 1/4m - 10 1/2m.

-50-10=-60

-(1/4)-(1/2)= (1/4)+(1/2)

(1/4+1/2)=(2/8+4/8) you can only add with the same denominators.

=6/8 (simplifies down to 3/4)

I need help with this ​
Hatshy [7]

Answer:

Step-by-step explanation:

1- angle JZF

supplementary angle or straight angle =180 degree

HZJ+JZF=HZF straight angle

2- JZA

complementary angle or right angle =90 degree

HZJ+JZA=HZA ( right angle)

if angle HZJ=38 degrees

HZJ+FZJ=180

FZJ=180-38

<h2>FZJ=142 degrees</h2>

HZG+HZJ=180

HZG=180-38=142 degrees ( which is vertical angle to FZJ and equal to it)

HZG=142 degrees

AZJ+HZJ=90 degrees

AZJ=90-38

AZJ=52 degrees

PLS HELP In circle A, secant EC and tangent BC intersect at point C. mЕВ = 171° and mBD 83°. What is mBCD?
liubo4ka [24]

Answer:

∠ BCD = 44°

Step-by-step explanation:

the secant- tangent angle BCD is half the difference of the intercepted arcs, so

∠ BCD = \frac{1}{2} (EB - BD) = \frac{1}{2} (171 - 83)° = \frac{1}{2} × 88° = 44°

X f(x)
lubasha [3.4K]
Remember slope formula is y=mx+b m is the slope b is the y intercept

Part a-1+5/0+1 = 4/1 that just equals 4 slope of g(X) is 4

part b y = 4x + b -1 = 4(0) + b -1 = b so y = 4x - 1

the function g(x) has a bigger y intercept (or where it crosses y on a graph) y intercept of g(x) is 3 and the y intercept of f(x) is -1

This really helps if you graph it

In 2018 there were 238 Republicans and 201 Democrats in the House of Representatives. Find the percentage of Democrats in the Ho
AnnyKZ [126]

Answer:

45.7% or if rounded, 46%

Step-by-step explanation:

1st, you add up the total of people in the House of Representatives.

238+201=439

Then divide the number of Democrats 201 by the total number 439 to get .457  which is 45.7% or if you need to round 46%

To double check, multiply the total number 439 X 45.7% to get 200.6
